|
This could be because you hit a bug. It is also possible that this binary
|
or one of the libraries it was linked against is corrupt, improperly built,
|
or misconfigured. This error can also be caused by malfunctioning hardware.
|
|
|
To report this bug, see https://mariadb.com/kb/en/reporting-bugs
|
|
|
We will try our best to scrape up some info that will hopefully help
|
diagnose the problem, but since we have already crashed,
|
something is definitely wrong and this may fail.

|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 61982 K bytes of memory
|
Hope that's ok; if not, decrease some variables in the equation.

I see that the latest failure on http://buildbot.askmonty.org occurred on 10.5 0d5d8d2e7a1debece188f355ecd7b098 on 2019-07-30 10:07:48 (over a year ago!).
The failure seems to be rare to begin with. There have been several fixes related to buffer pool resizing since then, including MDEV-21239, MDEV-22611, MDEV-22646. Can we close this bug?
Fresh occurrence:
